Embodiment
Illustrate by reference to the accompanying drawings embodiment of the present utility model.
Gearbox control system is comprised of air path part and circuit part two aspects.Wherein circuit part is by internal system cable 2, and External cable 3 and far module cable 15 3 parts form.Compared to gas circuit control assembly in the past, this control system has increased the monitoring to TOT Transmission Oil Temperature, oil pressure, air pressure, rotating speed by controller maincenter.In the process of wheel box running, by the judgement to these data, realize Gearbox Fault early warning and fault alarm.In fault alarm situation, can automatically control gas circuit and disconnect, speed change box clutch is thrown off, realize and shutting down.
Control enclosure inner air path is by retaining valve 201, baroceptor 206, and solenoid valve 202 grades partly form, and its major control mode is: press clutch switch, pressurized air is entered by control box left side air intake opening 204, via retaining valve 201, leads to solenoid valve 202.Solenoid valve is controlled by controller 1, controller meeting output current (voltage) signal in the situation that allowing clutch coupling combination, and solenoid valve 202 is opened, and pressurized air leads to gas outlet 203 through solenoid valve and makes clutch coupling inflation, completes clutch coupling combination.Under abnormal condition, controller can judge automatically, and the rotating speed by the current air pressure of judgement system and engine determines whether solenoidoperated cluthes combination, and both controllers not up to standard stop signal output, do not make solenoid valve combination.
Under wheel box normal operation, controller is by pick-up transducers signal, wheel box ruuning situation is judged, after this part data exceeds predetermined scope, controller can carry out the early warning of fault, in early warning situation, alarm lamp is the hummer buzzing of flashing, controller 1 panel alarm lamp Chang Liang, now wheel box still can continue operation, and controller can not thrown off by solenoidoperated cluthes.If but do not intervene, the in the situation that of continuing to raise (continue to change and exceed early warning range) at this partial data, controller can carry out fault alarm, the now hummer buzzing of flashing, controller panel trouble light Chang Liang, controller stops the electric signal that output solenoid valve is opened, and automatic control electric magnet valve is closed, realize throw-out-of clutch, wheel box is out of service.In clutch coupling, remaining pressurized air, by solenoid valve opposite side gas outlet, is discharged outside control system via sound suppressor 208.
Wheel box control box panel provides emergency stop switch, under special circumstances, can realize by emergency stop switch the emergency stop of wheel box.In wheel box control box bottom, be provided with emergency commutator switch 205, when running into special operation condition or controller and break down, can directly stir emergency commutator switch, skip controller steering logic, only by a close/minute button control clutch coupling of clutch coupling, closed minute, or claim that this pattern is combat model.
Wheel box control box is connected with External cable by aviation plug, and wherein system External cable 3 is connected by 17 core air plugs 207, and far module cable 15 is connected by 4 core air plugs 209.
Gearbox control system can be equipped with remote controllers 4, by RS485 interface, utilize MODBUS RTU communications protocol to realize communication, on far module, can realize the function of all local controllers, as clutch coupling closes minute control, wheel box data monitoring, fault pre-alarming and warning, fault inquiry, parameter modification etc.Far module is connected with local control box by four line connectors, and maximum communication distance can reach 1000m.
